Application filed January 18, 1904. Serial No. 189,579.

To It]! who/1t ii may concern:

Be it known that I, HARRY IVILLIS, a citizen of the United States ofAmerica,and a resident of Des Moines, Polk county, Iowa, have invented anew and useful Tobacco-Pipe, of which the following is a specification.

The object of this invention is to provide improved means for smokingtobacco in which the saliva and nicotin are absorbed to a material andconsiderable extent and collected for removal.

A further object of this invention is to be found in the provision ofimproved means for cleaning and replenishing the parts of a tobacco-pipewith which the tobacco comes in contact during the operation of smokingthe tobacco.

My invention consists in the construction, arrangement, and combinationof elements hereinafter set forth, pointed out in my claims, andillustrated by the accompanying drawings, in which Figure 1 is a detailsectional View of a metallic band or ring employed on my device. Fig.2is a perpendicular section of a detachable tobacco-bowl employed on mydevice. Fig. 3 is a perpendicular section of an absorbent bowl orliningemployed in my device. Fig. A is a perpendicular section of the bowlportion or body portion of my improved pipe, the absorbent bowl orlining and the tobaccobowl being removed. Fig. 5 is a perpendicularsection of my improved pipe, all of the parts being assembled asrequired for use.

In the construction of the device as shown the numeral designates thebowl portion or body portion of a tobacco-pipe, preferably made of woodand shaped as desired to suit varying tastes. The bowl portion 10 isformed with a cavity or chamber 11 and a duct 12, leading tangentiallyfrom the bottom of the cavity. The extremity of the duct 12 is enlargedfor the reception of a stem 13 and is of materially greater diameterthan the duct or passage 14. in said stem. An annular groove 15 isformed in the upper portion of the bowl portion 10 and opens to andsurrounds the cavity 11 therein. A by-pass duct or passage 16 is formedin the bowl portion 10 and afiords communication between the duct 12 andthe annular groove 15.

An absorbent bowl 17 is provided, preferably of concavo-convex form, andis made of any desired absorbent material. The absorbent bowl 17 isremovably and replaceably mounted in the cavity 11 of the bowl portion10 of the pipe, and the lower closed end of said bowl 17 closes andfills the lower portion of said cavity and crosses the lower end of theduct 12. Draft-ports 18 are formed in the wall of the bowl 17 andcommunicate with the groove 15 of the portion 10. Thus is provision madefor communication between the ports 18 and the duct 12 through thegroove 15 and by-pass 16 regardless of the position of said portscircumferentially of the bowl portion 10. The absorbent bowl 17 may beremoved and cleaned or thrown away when desired and be substituted byanother of identical character at the convenience of the user and whenin use receives and absorbs a material and considerable portion ofnicotin and saliva, both from direct contact with passing smoke and fromthe draining of the duct 12 thereto.

A tobacco-bowl 19 is provided, preferably made of hardened clay or otherheat-resisting and porous material, and is removably and replaceablymounted with its lower end portion in the absorbent bowl 17 Draft-ports20 are formed in the lower and otherwise closed portion of thetobacco-bowl19, and said ports communicate with the cavity of the lowerportion of the absorbentbowl. An annular boss 21 is formed on the upperportion of the tobacco-bowl 19 and is exteriorly screw-threaded toreceive screw-threads 22 on the interior of the mouth of the cavity 11.The tobaccobowl 19 is seated in the cavity 11 by screwing the annularboss 21 into the mouth of said cavity, and the lower portion of saidbowl is received loosely in but not in contact with the concave-convexportion of the absorbent bowl 17. The upper portion of the annular boss21 of the tobacco-bowl is formed with screw-threads 23, pitched in adirection reversely to the threads on the lower portion thereof, and ametallic band or ring 2 1, which may be plain or of ornate form, isscrewed on said threads 23 and rests against the outer margin of themouth of the bowl portion 10, while the lower margin of the boss 21rests on the outer end of the absorbent bowl and holds it on the bowlportion.

I claim as my invention 1. A tobacco-pipe, comprising the bowl por tion"formed with an interior annular groove near its mouth, the stem portionon the bowl portion, an absorbent bowl in the bowl portion and formedwith ports communicating with said annular groove, a tobacco-bowl in andformed with ports communicating with the absorbent bowl, and draft-portsin the bowl portion and stem and communicating with said groove.

2. A tobacco-pipe, comprising a bowl portion formed with a cavity and aduct leading tangentially from the bottom of said cavity, the stemcommunicating with said duct, the by-pass communicating between the ductand cavity above the opening of the duct to the cavity, the groove inthe cavity of the bowl portion communicating with said by-pass, theabsorbent bowl in the cavity and formed with draft-ports communicatingwith said groove,

the tobacco-bowl in the absorbent bowl and formed with draft-portscommunicating with the cavity of the absorbent bowl, and a band on thetobacco-bowl.

3. In a tobacco-pipe, the combination of the bowl portion formed with acavity, a groove opening to said cavity, a duct leading tangentiallyfrom the bottom of the cavity and a by-pass communication between theduct and groove, an absorbent bowl in the cavity and formed with portscommunicating with said groove, a tobacco -bowl in said cavity andformed with a draft-port communicating with the cavity of the absorbentbowl, and a stem for said bowl portion.

4. In a tobacco-pipe, the combination of the bowl portion and stem, theabsorbent bowl in the bowl portion, thetobacco-bowlscrewed in the bowlportion and contacting with the absorbent bowl, and a band screwed onthe tobacco-bowl.
